The BME280 can be used with I2C or SPI interface, see the BME 280 datasheet.
Check https://www.waveshare.com/wiki/BME280_E ... tal_Sensor
To use I2C, you should connect the SDA, SCL to the RPI header pin 3, 5 aka GPIO2, GPIO3 and leave CS open (or connect to 3.3V).
Connect ADDR to GND of RPi.
And of course you need to enable I2C with raspi-config.
